the way that thing hooks makes me want to ditch these leaf springs so damn bad... Thats the KP bolt in 4 link right??
how adjustable is it? I'm looking at well over 600 to the wheels on a track tune up with the new motor.... the leafs just arent going to do it anymore im afraid...

It's also a parallel 4-link which means it's IC length in infinite. This usually results in anti-squat well under 100%, causing the back end to squat and the front to rise. This might sound great, but higher anti-squat values can be beneficial because it provides the tires to be loaded and pushed into the pavement.
But I agree with you, in an EC, the instant center the leaf springs provide is ALL WRONG. It can work with RCs' 2ft shorter wheelbase, but I think its a hinderance in an EC.

The KP 4-link isn't adjustable at all. It could made a little bit adjustable by drilling some more holes, but I'm not sure how many holes you could get. Some new plates might have to fabricated. Also the links on the kp setup are only adjustable on one end, so pre-load adjustments and pinion angle adjustments are a little more difficult.

Vanilla, what do you mean not adjustable ? The bars adjust in length quite a bit on both sides and the shock mounting plate has several holes as well as the bed height by the 4 link. Are we talking the same setup? I hit up their site and couldn't tell if the new setups are the same as my old one.

Here is a typical drag race 4-link vs. the kp components version.

You can see that the drag setup has the provisions for the links to be mounted in different positions and angles. This allows adjustment for the instant center for varrying track conditions and launch/handling characteristics. Adjustability can be a real PITA though if you screw it up and don't know what you're doing.

Yes, the lengths are adjustable (pinion angle and preload), but instant center location is not.
